SPRINKLER FOR FIRE FIGHTING INSTALLATION Russian patent published in 2018 - IPC A62C31/02 B05B1/04 

FIELD: fire safety.

SUBSTANCE: invention relates to firefighting equipment. Technical result is achieved by the fact that a sprinkler fire extinguishing system consisting of a water supply source, a network of main and distribution pipelines with sprinkler heads, further comprises a main water feeder with a filter inserted into the source and connected to the main pipeline, and a make-up system installed parallel to the main water feeder line and including a make-up water supply pipeline of an auxiliary water feeder and an auxiliary (automatic) water feeder, and the control and signaling system includes a control and signaling valve and a signaling device, for example, in the form of a sound siren, wherein the main pipeline is connected to a network of distribution pipelines in which sprinkler heads are mounted, each of which is made in the form of a nozzle with a through hole and a threaded part that transitions into an end valve part, wherein the nozzle by means of an axisymmetric bracket consisting of two vertical volume stiffeners and two inclined prismatic ribs rigidly connected thereto is rigidly connected to a hollow cylindrical bushing with an internal thread interacting with a clamping bolt, which pushes the glass flask against the poppet valve, while on the other side to the sleeve, perpendicular to its axis, the spraying device is installed in the form of a socket with petals located relative to each other with a gap, and axially symmetrically on the side of the nozzle opposite the threaded part, a locking poppet valve is connected through the gasket, said valve connected with an element automatic triggering upon exceeding a set room temperature, which is made in the form of a glass bulb, which is a thermal lock.

EFFECT: technical result is increase in efficiency of fire extinguishing due to introduction of high-speed elements in general circuit of automatic fire extinguishing system.
